The arrival of a new baby in the family brings immense joy, and it's understandable that many parents desire to have more children soon after the birth of their first child. However, spacing pregnancies too closely can lead to a range of risks for both the mother and the fetus.

 

The Risks of Spacing Pregnancies Too Closely for Mother and Fetus

The gap between one pregnancy and the next can significantly impact the health of both the mother and the fetus. For mothers who have had a cesarean section, a longer recovery time is needed before they are physically prepared for another pregnancy. Additionally, factors such as the parents' mental and financial readiness also play a crucial role in preparing for a new pregnancy. From a maternal health perspective, there are several risks to consider if pregnancies are spaced too closely:

1. Risks of Premature Birth

Mothers who have pregnancies too closely spaced together are at a higher risk of preterm birth. This is often due to the physical stress and fatigue carried over from the previous pregnancy, increasing the likelihood of delivering prematurely in subsequent pregnancies.

2. Risks of Low Birth Weight (LBW)

Studies have shown that mothers who become pregnant within six months of their previous birth face a greater risk of delivering a low birth weight (LBW) baby. A baby is considered LBW if their birth weight is less than 2500 grams. LBW babies often require intensive care to improve their health and development.

3. Newborns Cannot be Exclusively Breastfed

When pregnancies are spaced too closely, it often leads to newborns not being exclusively breastfed. Exclusive breastfeeding is the optimal nutrition for newborns. However, mothers who are breastfeeding during pregnancy may experience a decrease in milk supply, along with fatigue and discomfort. These factors can hinder their ability to provide their babies with the benefits of exclusive breastfeeding.

4. Risks of Autism

Research from the Mayo Clinic has indicated that closely spaced pregnancies may increase the risk of autism in subsequent children. This risk is particularly high when the pregnancy occurs less than 12 months after the previous birth.

What is the Ideal Spacing Between Pregnancies?

Many experts recommend that a healthy gap between pregnancies for both the mother and baby should be at least 18 months. However, this gap may need to be longer if the mother has a history of pregnancy complications, has undergone a cesarean section, or has other health conditions that could affect her pregnancy.

According to the World Health Organization (WHO), the ideal spacing between pregnancies is three years. This allows the mother enough time to exclusively breastfeed her previous child and to recover from a cesarean section if applicable.

Additionally, it gives her body the time to physically prepare for another pregnancy, leading to a smoother pregnancy and delivery.

 

Other Factors to Consider Before Having More Children

In addition to pregnancy spacing, there are other important factors parents should consider before deciding when to have more children. Some of these factors include:

Financial Condition

Having more children brings additional responsibilities and obligations for raising and caring for them. This also means increased living expenses. If your financial situation does not yet support having more children, it’s wise to discuss your plans with your partner and plan accordingly.

Parental Mental Readiness

You might feel ready for a second child after successfully caring for your first, but it’s important to keep in mind that pregnancies spaced too closely together can divide your energy and attention. If both you and your partner feel unprepared to handle the responsibilities of multiple young children, it may be better to wait before planning another pregnancy.

 

Closely spaced pregnancies come with various risks for both the mother and the fetus. To minimize these risks, consider using contraception to manage the timing of your pregnancies wisely. Speak with your doctor about pregnancy planning and choosing the most suitable contraceptive method for you and your partner.
